8 Claims. 1 This invention relates to new and useful improvements in wire tying or splicing devices and the primary object of the present invention is to provide a wire tying mechanism for use in tying the ends of wire together on hay balers and more baler.

Another important object of the present in-- vention is to provide a wire tying mechanism including a rotatable gear having a slot for receiving a pair of wires or the ends of a wire and a novel and improved means for gripping the wire or wires so that as the gear is rotated the wire or wires will be twisted.

A further object of the present invention is to provide a wire tying mechanism including a plurality of wire twisting members and a mechanism for simultaneously ejecting wires from all of the twisting members.

A still further aim of the present invention is to provide a portable manually operated wire tying mechanism for baling machines that is simple and practical inconstruction, strong and reliable in use, efficient and durable in operation, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the de tails of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view of the present invention;

Figure 2 is an enlarged fragmentary side elevational view of Figure 1;

Figure 3 is an enlarged fragmentary rear elevational view of Figure 1 and with parts broken away;

Figure 4 is an enlarged transverse horizontal sectional view taken substantially on the plane of section line 4-4 of Figure 1;

Figure 5 is a fragmentary perspective view showing the tying member, the operating bar for the tying member, the retainers for wire engaged with the tying member, and the ejector bars;

Figure 6 is an enlarged vertical sectional view Referring now to the drawings in detail,

wherein for the purpose of illustration, there isdisclosed a preferred embodiment of the present invention, the numerals Ill and [2 Fig. 3, represent a pair of elongated back-to-back angle iron members that are connected together by any suitable number of cross straps. The opposing flanges I6 and I6 of the members l0 and I2 are joined by bolts 20 that rotatably support ball bearing roller units 22 which are positioned between the flanges l6 and I8.

Slidably mounted on the roller units 22, between the fianges l6 and I8, is an elongated rack bar or actuating member 24 that extends between pairs of bearings 26 Fig. 4. The bearings 26 are removably secured to the members [0 and I2 by fasteners 28 Fig. 6-, and the bearings 26 include inner and outer portions that are secured together by bolts 30. The bearings are provided with axial bores 32 and the outer portions of the bearings are formed with elongated openings or slots 34 that intersect the bores 32.

A wire tying member 36 is associated with each pair of bearings and the members 36 Fig. 5, each include a tube or hub 38 having a driven gear or pinion 40 fixed thereonintermediate its ends.

The gears 40 are provided with radial or in- 2, that is mounted on the members It and I2 at their upper ends. A pair of arms 48 rise from the platform 46 and support bearings 50 through which a shaft 52 extends to support a handle 54.

A driven gear 56 is keyedon the shaft 52 between the bearings 50 and meshes with the upper end of the rack bar 24.

Means is provided for holding wires withinthe tubes 38 and the 'slots42 of the gears 40. This means in the present instance consists of pairs of channel shaped guides or supports 56, Figs. 5 and 8, that are fixed by welding or the like to the members 10 and I2. The guides 56 are disposed at the ends of the tubes 36 and support pivots 58 that extend through clamping arms '80 having upwardly curved outer end portions 62.

The arms 60 are provided with openings or ball seats 64 that receive balls 66. Coil springs 68 are biased between the balls 66 and the upper walls of tubes 38 and the slots 42 in the gears 40. This,

means comprises upper and lower rods or bolts 14 and 16, Figs. 2, 3, and 4, slidably carried by the members [8 and I2. The bolts 14 are conheated by an upper cross strip 18 and the lower bolts 16 are connected by a lower cross strip 88.

'A pressure plate 82 is terminally secured to the strips 78 and 88. Coil springs 84 surround the bolts 14, 16 and are biased between the strips I8, 80 and the members l0, 12 to yieldingly urge the plate 82 from the rear of the members [0 Longitudinally extending ejector bars 86 and 88, Fig. 5, parallel the rack bar 24. The upper ends of the bars 86 and 88. are secured to the forward ends of the bolts 14 and thelower ends of the bars-86 and 88 are secured to the forward ends of the bolts 16.

The bars 86 and 88 are normally urged against the members 10 and I2 by" the springs 84 and are located between the ends of the tubes 38 and the guides 56. The bars 86 and 88 also extend transversely of and past all of the tubes 38 so that as the plate 82 is forced against the flanges l6 and IS, the bars 86 and 88 will be moved laterally across the tubes38 to force wires from the tubes 38 and the gears 40 by way of the In practical use of the invention, the parallel ends of a wire or two wires W are extended into the tubes 38 by placing the wires in the openings 34, slots 44 and 42; The wires are also extended under the arms 60 and against'the plates 10.

As the gear 56 is rotated,the rack bar 24 will slide and cause the gears 40 to rotate and since the arms 68 hold the wires tight, only the portions of the wires gripped by the gears 40 and between the arms 60 will. rotate, I to be twisted as showninFigure'5'. W

After the wires have been twisted, the plate 82 is forced toward the flanges l6 and I8 and the bars 86 and 88' will force the wires from the tubes 38 and gears 40, itbeing 'under'stoodtlia't the slots 42 and 44 will be in registry with the openings 34 as the'ejector bars are actuated. The sliding'of the rack bar may be limited by an enlarged tooth T on the gear 56 sothat the slots 42 and 44 will bein registry with the openings 34..after' the gears 40 have been rotated sufiiciently to twist the wire.

A roller R is mounted on the lower end of one of, the angle iron members forthe mounting on a track along side of -a baler.

.In view of the foregoing description taken in 4 A more detailed description is accordingly deemed unnecessary.
